Is the node fully healthy or rejecting some requests ?
What are the outputs for "grep -i "ERROR" /var/log/cassandra/system.log"
and "nodetool tpstats"?
Any error? Any pending / blocked or dropped messages?
Also did you try using distinct ports (9160 for thrift, 9042 for native) -
out of curiosity, not sure this will help.
What is your version of cqlsh "cqlsh --version" ?
doesn't work most times. But some time it just work fine
>
Do you fill like this is due to a timeout (query being too big, cluster
being to busy)? Try setting this higher:
--connect-timeout=CONNECT_TIMEOUT
Specify the connection timeout in seconds (default:
5 seconds).
--request-timeout=REQUEST_TIMEOUT
Specify the default request timeout in seconds
(default:
10 seconds).
